Abstract:

To establish the high performance liquid chromatographic (HPLC) fingerprint of Tenghuang Jiangu Wan (THJGW) and improve its quality standard,a Waters Symmetry C18 column (150 mm×2.1 mm, 3.5 μm) was used and a gradient elution with 0.1% formic acid in water (A) and 0.1% formic acid in acetonitrile (B) was performed as the mobile phase. The flow rate was 0.4 mL/min, the column temperature was 30 ℃, the injection volume was 2 μL and the detection wavelength was 260 nm. The fingerprint of THJGW was established and analyzed for its similarity by using the “Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System (2012 version)”. The identification of common peaks was characterized by ultra performance liquid chromatography-quadrupole time of flight-mass spectrometry (UPLC-Q TOF-MSE) combining with reference standards. The relative retention times and relative peak areas of common peaks in the fingerprints of 10 batches of Tenghuang Jiangu Wan were calculated. A total of 20 common peaks were determined in the fingerprints of 10 batches from THJGW, and the similarities were all above 0.95. Based on the information of reference standards and tandem mass spectrometry, the structures of 13 components in the common peaks were identified. And then, the corresponding Chinese medicines for each peak were attributed. The relative retention times and relative peak areas of common peaks in all batches of samples were relatively stable, corresponding to a constant content of ingredients. The similarity of the intermediates was evaluated using this fingerprint and showed a good correlation between intermediates and finished products. This method is precise, reproducible and stabilized. It can be used not only for quality control of the finished product of THJGW, but also for the detection of the intermediates.
